Preparation and characterization of insoluble dietary fiber from jujube residue and its physicochemical characters
In order to make use of jujube residue, insoluble dietary fiber from jujube residue was prepared by using auxiliary alkal method. The functional characteristics of insoluble dietary were also studied ,such as water holding capacity, expansibility and fat adsorption capacity. The optimum parameters obtained by orthogonal experiment were as follows : NaOH concentration 0.4mol/L ,soaking temperature 50 ℃, soaking time 120 min and milled size 60 mesh.Under this condition ,yield of insoluble dietary fiber was 73.1%. The water holding capacity, expansibility and fat adsorption capacity of insoluble dietary fiber were 4.9g/g, 4.6mL/g , and 3.2g/g , respectively. The extraction yield of dietary fiber from jujube residue was higher ,and its physicochemical characteristic was good. There are good prospects for development.
